NHTSA Complaint #11465013 — 2017 GMC ACADIA

Loss of power steering: bought NEW late 2017: In 1st month a whining noise was present while turning the steering wheel in any direction (driving or in park) even when slightly turning the wheel. At the time, didn't seem to effect anything. Difficulty started around 80k miles & continued to get worse as time went on. Each time varies on type of turn, speed of turn, how long the car has been in use. On average: it starts (& continues to get worse) after the first 10/15 minutes of driving. Loss of steering comes & goes (not only happening while turning) for at least 4 -15sec. In the last year (mid 2021 - 2022) went to mechanic -couldn't find an issue. Husband checks fluid levels monthly (no changes/no leaks are visible ). As of May 2022 (130k miles) turning into parking lots/spots/driveways/etc I have NO power steering, my husband is barley able to turn the wheel during these events. Its unsafe to drive. Doesn't seem to be as bad if speed is 20mph or faster. Shudder issue (maybe @60kmiles): *We had this issue w/our 2012 Acadia too. Multiple GMC Certified mechanics have been used to correct this. Only one mechanic was able to witness the shuddering. All things tried have failed to correct it. First started happening between 35 - 55mph (now its at any speed: 10 - 80mph), speeding up used to make it shudder less, turning traction control off USE to make it shudder less. Plenty of forums abt this issue including all things tried & failed. No resolution. Shudder causes car to not accelerate at times. RPM jumps high & bounces around. AC would stop working (started @20k miles) it makes an air releasing noise when AC is in use. *2012 Acadia did this too. Adding Freon helps for limited time. No leaks. Mechanics "CND", its still not fixed. "Tighten fuel cap" warning comes on randomly. When checked, its tight. Automatic start fails randomly, since day 1. "Ck Engine" light comes on & off randomly. Main issue was the shuddering *Reporting date used for loss of power steering.
